First, to address the slight class imbalance in the dataset, the Synthetic Minority Over-sampling Technique (SMOTE) [44] was initially applied to increase the instance count of each class to match that of the most populated class. However, as the imbalance was small and SMOTE yielded no signi...

imbalanced : True or False, default=False Specifies whether to use SMOTE technique for imbalanced datasets. Input Arguments for old syntaxdataname: could be a datapath+filename or a dataframe. It will detect whether your input is a filename or a dataframe and load it automatically. target: ...
SMOTE implementation ML models typically perform better with larger and balanced datasets; however, our data presents limitations in both these dimensions. The issue of significantly skewed or imbalanced data is well-recognized across various fields, particularly in health-related data. This includes subs...
class. Although ROS adjusts the class distribution, it may increase the overfitting problem by making similar copies of the minor class that influence the classification process [14]. Another standard oversample approach is the synthetic minority oversampling technique (SMOTE) [15]. It is used to...
Since some LULC classes (e.g. urban classes) were highly underrepre- sented, all classes except the most prevalent one were oversampled with the Synthetic Minority Over-sampling TEchnique-Nominal Continuous (SMOTE-NC) algorithm38 provided in R package "RSBID" to a sample size equivalent to ...

The best way to balance the database was using a technique called SMOTE [42,43]. The SMOTE technique for balancing the dataset was chosen because it is an oversampling technique, which would decrease the difference between the majority class (which are the non-dropping out students) and the...
